This study investigated how emotional language usage impacts self-referential effects in memory in healthy older adults and individuals with amnestic mild cognitive impairment (aMCI). To heighten self-focus, 37 healthy older adults and 22 aMCI participants narrated autobiographical memories and then encoded words using a self-referencing or a semantic strategy. We were interested in how narrating autobiographical memories impacted subsequent memory. We probed narrative language usage with the Linguistic Inquiry and Word Count text analysis program, testing the degree to which language from the narrated autobiographical memories contain emotional (positive and negative) words that predicted the self-reference effect across groups. Results indicated that higher levels of positive emotional language were related to larger self-reference effects in memory. In conclusion, narrating autobiographical memories using emotional language influenced the effectiveness of self-referencing as a memory strategy for both healthy older adults and aMCI participants.
本研究调查了情感语言的使用如何影响健康老年人和遗忘型轻度认知障碍(aMCI)患者记忆中的自我参照效应。为了增强自我关注,37名健康老年人和22名aMCI参与者叙述了自传体记忆,然后使用自我参照或语义策略对单词进行编码。我们感兴趣的是叙述自传体记忆如何影响后续记忆。我们使用语言查询和单词计数文本分析程序探究了叙述语言的使用情况,测试了叙述的自传体记忆中的语言包含情感(积极和消极)词汇的程度,这些词汇预测了各组的自我参照效应。结果表明,积极情感语言水平较高与记忆中较大的自我参照效应相关。总之,使用情感语言叙述自传体记忆影响了自我参照作为健康老年人和aMCI参与者记忆策略的有效性。
